well, it is possible with some larger adf A3 scanners that you can set
the paper guides narrow, and scan a piece of A4 in portrait mode, or
you can set the guides wide, and scan the same paper in landscape
mode.

in one case the paper is 210 × 297, in the other it is  297 x 210.

here is an odd question- are there any scanners with adf feed
right-to-left, but read head from top to bottom?
